Automotive 77GHz radar chip from ST

STMicroelectronics announced it is now supplying its latest long-range (77GHz) radar chips to leading automotive customers.

ST is already a top supplier of 24GHz systems. 24GHz systems are used in on-board automotive radar by enabling affordable, short- and mid-range smart-driving features such as blind-spot detection, collision avoidance, and lane-departure warning. ST said it has delivered over 35 million 24GHz radar transceiver ICs to date, and continues to build its customer base as more and more markets demand vehicles enhanced with ADAS.

"Today’s most developed markets are ready for next-generation features like high-speed adaptive cruise control that require high-power-output, long-range radar, which is best implemented using 77GHz technology. The higher frequency allows smaller antenna sizes, and permits the same technology to be used for ADAS requiring short-range, medium-range, or long-range radar, hence simplifying system design and reducing time to market." explains ST.

The device contains three 77GHz transmitters and four receivers on a single chip, which enables customers to build smaller, lower-cost, and less complex systems compared with competing solutions in the market that are less highly integrated, claims ST. The multi-channel architecture of ST’s new 77GHz radar chip enhances object recognition and resolution that translates into superior performance and dependability on the road, as per ST.
